I agree with using Mike Graham at Virginia Speed. He can do 2.92 low gear sets and he does good work.

I believe the Chrysler 904. I got mine from Dave at Pro-Trans.
The Ford guys run a C-4 with 904 guts in the Pro-trans.

My Broader Performance C-4 2.92 low uses a GM 125C for the C-4 front planetary. Looks like the same GM planetary on my ATI 2.92 as well.
